Description

Technical Field

[0001] This utility model relates to the field of optical instrument testing technology, specifically to a tooling for assisting prism in detecting surface shape. Background Technology

[0002] Prisms are a very familiar optical element with a wide range of applications, commonly used in digital devices, scientific and technological fields, and medical instruments. There is currently a significant market demand for them.

[0003] The existing measurement method involves picking up, placing, repositioning, image finding, measuring, and then removing the workpiece before repeating the process for the next workpiece. This method is inefficient and the placement position is not fixed each time, requiring repeated movement and re-alignment. This is time-consuming, labor-intensive, and can damage the surface finish of the workpiece.

[0004] Moreover, there is currently no measurement solution to improve detection efficiency. We can only measure each prism manually or conduct random checks, but the quality of the random checks cannot reach 100%.

[0005] In summary, it is necessary to design a tooling to assist prism in detecting surface shape in order to improve work efficiency and reduce the burden of repetitive operations for staff. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to provide a tooling for assisting prism surface detection, including an adjustment frame set at the bottom. The adjustment frame is movably arranged on an external air cushion platform. Vertical support sidewalls are integrally provided on both sides of the adjustment frame. A manual push-pull rod is movably inserted through the two support sidewalls. A connecting plate is fixedly inserted through the middle of the manual push-pull rod. The bottom of the connecting plate slides against the top surface of the adjustment frame. A row of detection areas is arranged on the front and rear sides of the top surface of the connecting plate. The detection area is composed of multiple limiting blocks connected in sequence. Each limiting block has a limiting groove on its outer side that can accommodate the workpiece to be tested.

[0007] In the above scheme, the planar shape of the limiting groove is a right triangle, and one of the right-angled sides is arranged to open outwards.

[0008] In the above scheme, the planar shape of the limiting groove is a right triangle, and the hypotenuse is arranged to open outward.

[0009] In the above scheme, the surface of the manual push-pull rod is provided with scale dimensions.

[0010] In the above scheme, the arrangement direction of the limiting blocks is consistent with the movement direction of the manual push-pull rod.

[0011] In the above scheme, the bottom of the adjustment frame is integrally provided with a support leg that connects to an external air cushion platform.

[0012] In the above scheme, the two rows of limiting blocks are arranged in parallel to each other.

[0013] In the above scheme, the limiting block is composed of a prism with a surface finish better than 80 / 50 and an angle of ±1′.

[0014] This invention improves testing efficiency, reduces the workload of repetitive operations, and prevents damage to workpiece surface finish during measurement, without affecting other functions such as surface finish and appearance. Attached Figure Description

[0019] In this utility model, unless otherwise stated, the scientific and technical terms used herein have the meanings commonly understood by those skilled in the art.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] It should be noted that in the description of this utility model, the terms "first" and "second" are used only for the convenience of describing different components and should not be construed as indicating or implying a sequential relationship, relative importance, or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0023] Terminology Explanation:

[0024] Right-angle prism:

[0025] Right-angle prisms are typically used to deflect light paths or rotate the image formed by an optical system by 90°. They can also be used for image combining, beam shifting, and other applications. Utilizing the critical angle characteristic, efficient internal total internal reflection of incident light is one of the basic functions of a right-angle prism.

[0026] Face shape:

[0027] The local irregularity of the interference fringes generated by the tested optical surface and the reference optical surface in any direction is called local deviation, also known as surface profile.

[0028] Smoothness:

[0029] Also known as surface defects of optical components, represented by the symbol B.

[0030] like Figure 1 and Figure 2 As shown, the present invention provides a tooling for assisting prism detection of surface shape, including an adjustment frame 1 set at the bottom. The adjustment frame 1 is movable and externally connected to the air cushion platform. The adjustment frame 1 can be adjusted left and right over a long distance without changing the vertical and horizontal distance.

[0031] The adjustment frame 1 has vertical support sidewalls 2 integrally provided on both sides. A manual push-pull rod 3 is movably inserted through the two support sidewalls 2. The manual push-pull rod 3 is a simple auxiliary push-pull device. It is inexpensive and easy to use. Then, the scale dimensions are marked on it to clearly indicate the distance of each push.

[0032] A connecting plate 4 is fixedly inserted through the middle of the manual push-pull rod 3. The bottom of the connecting plate 4 slides against the top surface of the adjustment frame 1. The two ends of the connecting plate 4 are connected to the manual push-pull rod 3, which can be pushed and pulled as a whole.

[0033] A row of detection areas is arranged on the front and back sides of the top surface of the connecting plate 4. The detection areas are composed of multiple limiting blocks 5 connected in sequence. The two rows of limiting blocks 5 are arranged in parallel to each other. The limiting blocks 5 are composed of prisms with a surface finish better than 80 / 50 and an angle of ±1′. This avoids damage to the surface finish of the workpiece when placing the prisms later.

[0034] Each limiting block 5 has a limiting groove 6 on its outer side that can accommodate the workpiece to be tested. The workpiece can be placed directly. The limiting blocks 5 are arranged in a straight line and their arrangement direction is consistent with the moving direction of the manual push-pull rod 3.

[0035] Further preferably, the limiting groove 6 has two functional structures. One is that the plane shape of the limiting groove 6 is a right triangle, with one right-angled side opening outwards. The other is that the plane shape of the limiting groove 6 is a right triangle, with the hypotenuse opening outwards. In this way, there are different limiting grooves corresponding to the right-angled surface and the hypotenuse, distributed on the front and rear sides of the connecting plate, which can be interchanged for use as needed.

[0036] In a further preferred embodiment, the bottom of the entire frame 1 is integrally provided with support legs 7 that connect to an external air cushion platform.

[0037] This invention allows for batch placement of workpieces during inspection, followed by positioning and image finding, resulting in multiple surfaces. Measurements can then be taken directly based on the selected diameter. Other workpieces can be measured sequentially by pushing a movable adjustment frame. This fixture is low-cost, simple to manufacture, and reusable. It is convenient to operate during inspection, improving efficiency and reducing the burden of repetitive operations for staff. Because of the limiting groove, multiple pieces can be placed at once and positioned correctly. Measurements are then taken one by one using the movable planar adjustment frame, avoiding repositioning and minimizing damage to the workpiece's surface finish during measurement.

[0038] This invention improves testing efficiency, reduces the workload of repetitive operations, and prevents damage to workpiece surface finish during measurement, without affecting other functions such as surface finish and appearance.

[0039] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
